Polymer plastic body worn case

ABSTRACT

The spread of wireless communication is growing. A handy holder provides an innovative cost-effective support for communication devices when controlling movements of people inside or outside of a building. The idea is to use a plastic case capable of repelling bacteria, a case with perpendicular walls adapted to support a rectangular radio. In preparing plastic walls, it is important to drill holes for broadcast waves and to provide openings for communication ON/OFF. Perpendicular corners are obtained by carving a width of plastic until there remains a thin wall which may be folded either internally or externally, thereby creating a link to a flared normal direction.

BACKGROUND OF THE INVENTION

The invention relates to the field of a body worn case for electronic devices such as for radio controlling of internal and external communications.

PRIOR ART

A study of the prior art has revealed the following:

CA1300096 a retainer bracket affixed to a wall of a plastic like case.

CA2368594 for a virtual battery.

U.S. Pat. No. 7,327,255 for a carrying case.

CA2097375 for a reusable plastic case.

OBJECTS OF THE INVENTION

It is an object of the invention to provide communication tool supports adaptable to a person transporting them. Another advantage of this invention is to provide a rectangular case element, which is washable and practical for use in communication.

Other objects and advantages of this invention shall appear from a careful reading of the detailed description attached and with reference to the drawings.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT

In the following description and in the accompanying drawings, the numeral numbers refer to identical parts in the various Figures.

In FIG. 1 a polymer case 20 has a front wall 22, a left wall 24 comprising a mike slot opening 25, a bottom wall 26, a right hand wall 30, a thickness 28, a back wall 42 which appears to be as partially removed, holes in the back wall to set the left and right walls and to set a hitch. The front wall has holes for speaker and sound waves 31 and a mike slot hole 33. The case bottom wall 26 has evacuation holes 32 for air and moisture. The bottom wall is covered by two bottom folds 36 held in place by two or more rivets 34 in rivet holes. The right wall has a central cavity 35 and shows a line of an outward score 38′ and another line for an inward score 39. Two folded wings 40 support the partially removed back wall 42; between right wall 30 and the bottom fold 36 there is an inward score 39″, similarly along the left side, between the front wall 22 and the left wall 24, there is an inward score 39 which proceeds as far as the start of the mike slot 25; also between the left wall 24 and the bottom fold 36 there is an inward score 39′″ and between the front wall 22 and the bottom wall 26 there is an inward score 39″″.

In FIGS. 2A, 2B, 2C, 2D show a wall thickness 28 with in FIG. 2A a minimum removal 48, which serves to connect an outward link 44, which becomes in FIG. 2B an external arc 44′ and leaving an outward score 38. In FIG. 2C there is a maximum removal 50 from a wall leading to an inward link 46, which becomes in FIG. 2D an enclosing arc 46′ circling an inward score 39. In short one sees the opening of the outward link 44, which is straight in FIG. 2A and becomes a curved external arc 44′ in FIG. 2B. One sees an inward link 46, which is also straight in FIG. 2C and is curved along an enclosing arc 46′ in FIG. 2D. One also sees in FIG. 2A a digging of a plastic depth appearing as a minimum removal 48 next a maximum removal in FIG. 2C in a second area of digging withdrawal permitting to close an inward link 46′ in FIG. 2D to surround the inward score 39.

In FIG. 3 one sees the inward score 39′ which reaches to about 3 mm from the mouth of the case showing an internal filling 54′ of original matter; it is also the inward score 39 which reaches approximately 3 mm from the mike slot 25 showing an internal filling 54 of original matter. This area of original matter approximately doubles the strength in tear resistance. Conversely an outward score 38′ reaches about 3 mm from the mouth of the case showing an outward filling 52′ of original matter which is shown on the outside and may be an outward link 44,44′, of FIG. 2A,2B; actually an elongated wing 41 must be turned 90° degrees inwardly to be superimposed against a fullback flap 43 that should not be longer than the front wall 22 to cover the sum of the length of the front wall 22 plus that of the two folded wings 40 as shown in FIG. 1. An original filling of more than 5 mm is not recommended and does not allow a fold as precise, defined and controlled to about 90° degrees. One may add other matter of origin, for example each distance of 35 mm or 45 mm. In addition there are rivets and holes 34 therefor.

FIG. 4 shows the embodiment of FIG. 3 laid flat as before the components are assembled and inter-related. One notice the references 54′,52′,39′ corresponding to the right parts identified as 54,52,39 to the left. There is a fullback flat 43 rear wall not exceeding the width of the front wall 22. The elongated wings 41 may exceed in length the side walls 24,30 left and right. Holes for rivets 34,34′ are positioned to be stacked when bottom fold 36 are rotated 90° degrees to cover the bottom wall 26.

SUMMARY OF THE INVENTION

A plastic body worn case 20 for portable electronic devices, the case comprising: a front wall 22, a back wall 42, two side walls 24 left and right 30, a bottom wall 26, a wall thickness 28, the walls being joined to form an open face paralelepiped and defining a number of junctions between the walls, at least one of the junctions including a partial removal of the thickness (t). Note the letter (t) added after the word thickness is to introduce a mathematical concept. The partial removal leaves a non-removed or of original matter to produce an inward link 46 which may be bent into an enclosing arc 46′ around an inward score 39 around which two walls are adjacent to and oriented 90° degrees one compared to the other. The arc length is larger than 1½ times the thickness (t) to close two adjacent walls in the clockwise direction, a right wall in relation to a second wall, the length of an inward arc defining a maximal removal 50. The external arc 44′ has a preferred external arc length equals to ½ times the thickness (t) to close two adjacent walls in anti-clockwise direction, one over the other, the length of external arc 44′ is smaller and defines a minimum removal 48. The walls are made of materials to be used in combination with illuminating means such as a soft plastic. The side walls are folded about the inward scores 39,39′ and include folded wings 40 originating from outward score 38′ (see FIG. 1) and connected by a back wall 42 (partially removed, FIG. 1) and of length corresponding to the length of the front wall 22 plus the length of the folded wings 40. The side walls are folded at the inward scores 39,39′ and include elongated wings 41 (see FIG. 3) appearing as outward scores 38,38′ for the purposes of illustration, but normally will be rotated 90° degrees to join the left side to the right side and become a pair of inward scores 39,39′ and the two elongated wings 41,41′ will be met by a fullback flap 43 back wall (see FIG. 3) in length corresponding to the length of the front wall 22. The side walls 30,24, the bottom wall 26 and the fullback flap 43 are assembled with the front wall 22 and with the bottom folds 36,36′. (see FIG. 4). The walls are made of plastic materials, synthetic materials, smooth or texturized to the touch with or without added materials.

It is to be clearly understood that the instant description with reference to the annexed drawing is made in an indicative manner and that the preferred embodiments described herein are meant in no way to limit further embodiments realizable within the scope of the invention. The matter which is claimed as being inventive and new is limited only by the following claims.
